plot.FastRCS {FastRCS}

Robust Diagnostic Plots For FastRCS

Description

Shows the robust Score distances versus robust Orthogonal distances and their respective cutoffs, for the an object of class FastRCS.

Usage

## S3 method for class 'FastRCS'
plot(x,col="black",pch=16,...)

Arguments

x

For the plot() method, a FastRCS object, typically result of FastRCS.

col

A specification for the default plotting color. Vector of values are recycled.

pch

Either an integer specifying a symbol or a single character to be used as the default in plotting points. Note that only integers and single-character strings can be set as a graphics parameter. Vector of values are recycled.

...

Further arguments passed to the plot function.

Details

This function produces the robust standardized, residuals as well as an indicative cut-off (under normal model). This tool is a diagnostic plot for robust regression and can be used used to reveal the outliers.
